1860.] been referred to instinct, doubtless, because they have one characteristic of instinct,—that they are not acquired by experience or instruction. "But they differ," says Professor Bowen, "at least in one important respect from those instincts of the lower animals which are usually contrasted with human reason. The objects towards which they are directed are prized for their own sake; they are sought as ends; while instinct teaches brutes to do many things which are needed only as means for the attainment of some ulterior purpose." When the butterfly extracts the nectar from the flowers which she loves most, she meets a want of her physical nature which demands satisfaction at the moment; but when, in opposition to her appetite, she proceeds to the flowerless shrub to deposit her eggs upon the leaves best suited to support her unthought-of progeny, she is not influenced by any desire for the immediate gratification of her senses, but is led to the act by some dim impulse, in order that an ultimate object may be provided for to which she has no reference at the time. We are surprised to find it declared, in the very interesting "Psychological Inquiries " of Sir B. C. Brodie, that the desire for food is the simplest form of an instinct, and that such an instinct goes far towards explaining others which are more complicated. It is true that the appetites and passions of animals have an ultimate object, but they are impelled to action by a desire for immediate gratification only; but when we speak of an instinct, we mean something more than a mere want or desire,—we have chiefly in view the end beyond the blind instrumentality by which it is reached.

When we watch the movements of a young bee, as it first goes forth from its waxen cradle, we are forced to recognize an influence at work which is unlike reason, and which is neither' appetite nor any mechanical principle of organic life. Rising upon the comb, and holding steadily with its tiny feet, with admirable adroitness the young bee smooths its wings for its first flight, and rubs its body with its fore legs and antennae; then walking along the comb to the mouth of the hive, it mounts into the air, flies forth into the fields, alights upon the proper flowers, extracts their juices, collects their pollen, and, kneading it into little balls, deposits them in the sacks upon its feet; and then returning to its hive, it delivers up the honey and the wax and the bread which it has gathered and elaborated. In the hive it works the wax with its paws and feelers into an hexagonal cell with a rhomboidal bottom, the three plates of which form such angles with each other as require the least wax and space in the construction of the cell. All these complex operations the bee performs as adroitly, on the first morning of its life, as the most experienced workman in the hive. The tyro gatherer sought the flowery fields upon untried wings, and returned to its home from this first expedition with unerring flight by the most direct course through the trackless air.

This is one instance of that great class of actions which are allowed on all hands to be strictly instinctive. In the fact, that the occult faculties which urge the bee to make honey and construct geometrical cells are in complete development when it first emerges from its cell, we recognize one of the most striking characteristics of instinct,—its existence prior to all experience or instruction. The insect tribes furnish us with many instances in which the young being never sees its parents, and therefore all possibility of its profiting from their instructions or of its imitating their actions is cut off. The solitary wasp, for example, is accustomed to construct a tunnelled nest in which she deposits her eggs and then brings a number of living caterpillars and places them in a hole which she has made above each egg; being very careful to furnish just caterpillars enough to maintain the young worm from the time of its exclusion from the egg till it can provide for itself, and to place them so as to be readily accessible the moment food is required. But what is most curious of all is
